Every year we lose some bulbs to squirrels, and every year I vow to take more action to fight them. There are many home remedies to keep squirrels away, including dusting cayenne pepper or blood meal on the soil or around the base of the plants as they start to emerge. (If you do this, don’t use more than a few ounces of blood meal, due to the high nitrogen levels.) Once the plants are up, you could spray with a mixture of 1 teaspoon of mild liquid dishwashing detergent and a healthy dose (2-5 oz) of Tabasco sauce, in 1 gallon of water, shake well and pour into a plastic spray battle.
Man your battle stations!
